Key to species of the genus Dendarus from Iran and Turkmenistan

(on females = not widened protarsi)

1 Elytra with sparse (19–24 punctures in one row), strongly elongate (at least 1–3 striae), deeply impressed strial punctures ( Figs 2F View FIGURE 2 , 3F View FIGURE 3 )............................................................................................. 2

- Elytra with denser (27–40 punctures in one row), round (only several punctures in 1–2 rows can be elongate), not impressed or slightly impressed strial punctures ( Figs 2C View FIGURE 2 , 4C View FIGURE 4 , 6C View FIGURE 6 , 8C, E View FIGURE 8 )................................................... 3

2 Body completely shiny. Puncturation of pronotum dense and coarse. Puncturation of elytral interstriae dense ( Fig. 2F View FIGURE 2 )............................................................................................... D. crenulatus

- Head and pronotum shiny, elytra dull. Puncturation of pronotum fine and sparse. Puncturation of elytral interstriae very fine and sparse, poorly visible ( Fig. 3F View FIGURE 3 )................................................................ D. leonhardi

3 Puncturation of pronotum uneven: very fine and sparse, with round punctures at middle and sharply coarse and dense, elongate, often merged punctures on lateral sides ( Fig. 6C View FIGURE 6 )................................................ D. transcaspicus

- Pronotum uniformly punctured with moderately dense or sparse round punctures, sometimes punctures on sides slightly denser, but not sharply ( Figs 2C View FIGURE 2 , 4C View FIGURE 4 , 8C, E View FIGURE 8 )...................................................................... 4

4 Posterior angles of pronotum obtuse, not protruding ( Fig. 2C View FIGURE 2 )...................................... D. armeniacus

- Posterior angles of pronotum right or acute, weakly protruding ( Figs 4C View FIGURE 4 , 8C, E View FIGURE 8 )................................... 5

5 Elytral striae 1 and 2 close to each other, second interstria narrower than third one ( Figs 8C, E View FIGURE 8 )........... D. vagabundus

- Elytral striae 1 and 2 not close to each other, second and third interstriae with the same width in middle ( Fig 4C View FIGURE 4 ).............................................................................................. D. matthewsi sp. n.
